1: All atoms have the same number of protons as electrons.
True
False
Need more information
2: When you rub a balloon on your sweater some of the electrons are transferred from the sweater to the balloon. The sweater becomes positively charged. the balloon will have negative charge.
True
False
Not enough information
3: Things stick together in static electricity because the ( ) charges on one material attract the (-) charges on the other
True
False
Not enough information
4: What happens to an atom if something pulls an electron from it?
It explodes
The atom has a positive ( ) charge
The atom has a negative (-) charge
5: If you pressed you hand on some teflon and then pulled them apart, what would happen?
Nothing, because you must rub them together to create enough friction
Your hand would get positive ( ) charges
The teflon would get positive ( ) charges
6: Rubbing which materials together would produce the most static electricity?
Leather and Teflon
Dry skin and cat fur
Wood and paper
7: What is the difference between a spark and lightning?
Lightning occurs in summer; sparks in winter
Lightning is just a big spark
Lightning makes noise but sparks don't
8: How can you minimize getting static electricity shocks?
Never wear shoes
Use something to drain off the excess charges
Always wear a metal hat on a dry day
9: What is a reason a lightning rod works?
The lightning rod is closer to the clouds and uses metal to conduct the electricity
The lightning rod has a sharp point to repel the lightning
The lightning rod needed Ben Franklin to work
10: What can be used to store static electricity?
High voltage
Type AA batteries
A Leyden Jar or similar capacitor
11: How can static electricity clean out cigarette smoke?
By giving smokers an electric shock
By giving smokers an electric shock
By charging and collecting smoke particles
12: What is an advantage of using static electricity to paint a car?
The paint goes on evenly
The paint will attract cigarette smoke
The paint collects at sharp points
13: Is it possible to levitate a small animal?
Only metals can be levitated
If the animal is lighter than air
Yes, since organic material is diamagnetic
14: Why is the Gauss used instead of the Tesla to describe the strength of a magnetic field?
Gauss is easier to spell
Officials were angry at Tesla, so they removed his name
The Gauss is smaller and easier to use
15: What does a magnet repel?
The opposite pole of another magnet
Iron, nickel and cobalt
The same pole of another magnet
16: How does a compass aid in navigation?
It detects the Earth's North magnetic pole
It detects the number of gauss from the Earth
It is only used to detect large magnets
17: What element has all or most electrons aligned in the same direction?
Nickel
Krypton
Stainless steel
18: If more electrons were flowing through a wire, what would be increased?
Voltage
Protons
Current
19: What is the equation for Ohm's Law?
V = I x R
V = I R
V = I / R
20: Who was responsible for AC?
Einstein
Edison
Tesla
thanks!!
